Angry little Roughy!
Posted: Fri Apr 10, 2020 4:03 pm
Well for those that may remember me briefly posting about a new build on my Roughy last fall...well shes almost broken in and pretty close to being dialed in. As per usual I didn't finish her up during the winter as I should have but the past week or so I've finished fabbing and bolting her together. This is a copy and paste of what I attempted to make as my signature that I typed out twice before realizing the site wouldn't allow that many characters.
2014 Roughhouse 50, Stage6 Sport Pro Mk2 70 (.085 squish), Yasuni C16.07 (City) because I like power and centerstands, Athena HPC full circle crank, 19mm Malossi Dellorto PHBG 102 main 42 pilot and W16 needle, stock air box snorkel removed w/two 1/2" holes on bottom and two tubes in the holes, Voca .35 carbon fiber reeds, Polini Hi-Speed variator w/4.20 gram Dr. Pulley sliders, Stage6 Torque Control clutch w/red (hard) springs, NCY torque driver, Polini tach/temp/voltage gauge part# 171.1001, premix only (oil pump disabled), LEDs all the way around. I'm sure I'm forgetting something.
Shes a naughty girl that will not accept anything below 8k RPMs. Trying to get the Stage6 clutch broke in so it'll actually grab from a standstill. May end up reinstalling my Polini For Race 3G clutch because she always launched hard with my last fairly mild build. We'll see though because it may be that nothing wants to grab from a standstill at 7500-8k. I'm still tinkering with needles and jets but I'll take that further once I feel confident that the cylinder is fairly well broke in. Powerband is peaky and fairly high for street use but it is doable and usable at about 8-12k+. I really need to test this quite a bit more before I state what it is and or isn't. So far I love it and I'm hoping that this Athena full circle crank cures the woes of the high revving builds I see on here. My stock rod had zero oil ports on the small end for feeding the needle bearing. The Athena has a nice pair of oil passage holes on the small end as any and every two cycle should. I might also be breaking up a bit up high but I'm not sure. I gapped the plug tighter and seemed to help a bit so I may get the Malossi CDI and higher energy coil. Anyway this is where I'm at with this so far so if anyone has any questions feel free to ask and if anybody wants to offer advice then I'm all ears. Thanks all
